Factorial Design - an overview | ScienceDirect Topics

A factorial design is obtained by cross-combining of all the factors' values. Fig. 2.1 displays a two-factorial design in which each factor is represented by a single dimension. The factors form a Cartesian coordinate system (i.e., all combinations of each level of each dimension). In Fig. 2.1, the first dimension is the variable that is assumed to affect the speed of processing of process one.

Dec 27, 2012 · A factorial design contains two or more independent variables and one dependent variable. The independent variables, often called factors, must be categorical. Groups for these variables are often called levels. The dependent variable must be continuous, measured on either an interval or a ratio scale. Suppose a researcher is interested in ...

Factorial experiment - Wikipedia

In statistics, a full factorial experiment is an experiment whose design consists of two or more factors, each with discrete possible values or "levels", and whose experimental units take on all possible combinations of these levels across all such factors. A full factorial design may also be called a fully crossed design.Such an experiment allows the investigator to study the effect of each ...
